Patent CA-2203308-A1 (CA)
Inventor: CHEN XIAOLIN
IPC: G01N21/35
Filed: 1997-04-22
Abstract: In a method for identifying an unknown product a library  of  absorbance  spectra  of  known products  is measured and stored in a library.  A quick search using clustering techniques is conducted to narrow the search to a few products, followed by an exhaustive search of the spectra of the few products.  More specifically, principal component analysis is applied to the absorbance spectra to generate product score vectors extending into principal component inside model space which are divided into clusters and subclusters in accordance with their relative proximity.  Hyperspheres are constructed around each vector and an envelope is constructed to enclose each cluster surrounding the hyperspheres within the cluster.  The absorbance spectrum of the unknown product to be identified is measured and an unknown product score vector is determined from the unknown product spectrum projecting in principal component inside model space of the clusters.   It  is determined whether or not the unknown product score vector falls within one of the envelopes and if so the product score vector is projected into the principal component inside model space of that cluster and it is determined whether or not the unknown product score vector falls within any of the subclusters divided from the cluster.  This process is repeated until the unknown product score vector is found to lie in a cluster which is not further subdivided.  In this manner, the search is narrowed to a few products. An exhaustive search is then carried out to match the spectrum of the unknown product with the spectra of the known products corresponding to the undivided subcluster.

Inventor: MUELLER HANS-JUERGEN
IPC: C01B32/40
Filed: 1997-06-20
Abstract: The present invention is directed to a process for simultaneously obtaining pure carbon monoxide and pure hydrogen in a steam reformer plant for hydrogen or ammonia generation, having a primary reformer, a secondary reformer and downstream thereof, a CO conversion stage. A part gas stream of the synthesis gas stream, which is discharged from the secondary reformer having a CO content of between 2 and 20 mol.% and is at a temperature of from 200 to 500°C and a pressure between 15 and 50 bar, is removed between the secondary reformer and the CO conversion stage. The part gas stream is then is cooled to a temperature below 100°C, thereby condensing out the major part of the steam contained in the gas stream. The remaining raw synthesis gas stream is then guided by way of a multistage gas separation plant in which the gas components H2, residual steam, CH4, CO2 and optionally N2 are separated, either individually or together, from the CO. The separated gas components are then compressed to a pressure which exceeds the pressure in the CO conversion stage and are recombined to form a mixed gas stream. The mixed gas stream is then guided into the CO conversion stage of the steam reformer after being heated to a temperature of from 200 to 500°C. The remaining pure CO fraction is removed in separate manner and may optionally, be supplied for further processing.
